The Advantage Tactical Sight (ATS) system is now available for the new Diamondback FS Nine. Like with many other guns, the ATS easily fits the DB FS Nine. The aligned front and rear sights of the ATS form a pyramid. You simply need to place the top of the pyramid to where the desired bullet impact will be.
